Dear student,
Following are the reasons for drinking water early in the morning empty stomach:-
1) Body dehydrates during sleep. So, it is necessary to refill the body as every cell performs reaction in presence of water.
2) During the whole night metabolism generates toxins in the body which needs to be flushed out and make the body ready for uptake of nutrients.
3) It speeds up the metabolism.
4) It removes constipation, acidity and cramps which causes gastritis.
5) It cures diseases like cancer.
6) It makes your skin glow and prevents premature wrinkle.
